The customer was experiencing regular bearing failure on their conveyor at a Milk Processing Plant. Due to the applicaiton and area in which the bearings were, they were difficult to lubricate. The customer had to change the bearings every 10 weeks, resulting in down-time of 3 hours each time. NSK reviewed the bearing application and suggested that stainless steel bearing inserts fitted with Molded-Oil would offer better service life. In addition it was suggested that they combine these with the additional benefits of Silver-Lube® polymer housings to provide the Life-Lube® combination. Tested bearings showed that bearing life was extended from 10 weeks to over 1 year.
